1 Claim.

The invention aims to provide an unusually simple, light and strong,stockless, marine anchor which will quickly and effectively bury itselfregardless of its light weight and will, therefore, be much moreeffective than even larger and heavier anchors, the constructions ofwhich not only retard effective burying but to a large extent preventit.

Figure l of the accompanying drawings is a plan view with part of theshank broken away.

Fig. 2 is a side elevation.

Fig. 3 is a rear elevation.

Fig. 4 is an enlarged fragmentary longitudinal sectional viewsubstantially on line 4-5 of Fig. 1.

Fig. 5 is a transverse sectional view on the plane of line 5-5 of Figs.1 and 2.

A preferred construction has been illustrated and will be ratherspecifically described, with the understanding, however, that within thescope of the invention as claimed, minor variations may be made.

Two main flukes 6 are provided, preferably having about parallellongitudinal edges behind their pointed front ends. Integral with therear end of each main fluke 6, is an upper, auxiliary fluke l whichinclines rearwardly. A lower, auxiliary fluke 8 is also integral withthe rear end of the main fluke 6 and declines rearwardly therefrom. Eachfluke l, 8 is preferably of substantially ccncavo-convex form inlongitudinal section with its concave side merging very gradually intothe contiguous side of the main fluke 6. The rigidly joined fiukes E, 1and 8 jointly provide two triplex fiukes having rearwardly open V-shaped pockets 9, which pockets also open laterally. I have found that atriplex fluke of this nature will not only be unusually light but willmore effectively bury itself than prior constructions with which I amfamiliar.

While the rear ends of the auxiliary fiukes l and 8 are free and this isalso true of the outer longitudinal edges of these auxiliary flukes, theinner edge portions of the upper flukes I are integrally connected withthe inner edge portions of the lower fiukes 8, by means of vertical websH] which are instrumental in joining the triplex flukes integrally tothe crown II. This crown is of one-piece U-shaped formation, with itsside arms l2 projecting forwardly from its arm-connecting portion 13.The front ends of the arms I2 are outwardly widened as shown at it andare integrally joined to the inner opposed sides of the webs W. Thearm-connecting portion [3 includes a rearward lug l5 having an openingis and 2 provides the equivalent of the conventional buoy shackle.

The rear end of a suitable shank I1 is received between the rear ends ofthe arms I2 and is pivoted thereto by means of a transverse pin l8.Above and below this pivoted end of the shank H, the arms 12 areintegrally connected by transverse webs l9 which constitute stops forlimiting the pivotal movement of the triplex fiukes and crown in bothdirections with respect to said shank, as well as adding strength to thestructure of the crown. The upper side of this crown is below the rearextremities of the upper auxiliary flukes 1, and the lower side of saidcrown is above the rear extremities of the lower auxiliary fiukes 8, andthe crown will not, therefore, interfere with effective burying of theflukes l or 8, regardless of which side of the anchor be down.

From the foregoing, taken in connection with the accompanying drawings,it will be seen that novel and advantageous provision has been made forcarrying out the object of the invention, and while preferences havebeen disclosed, attention is again invited to the possibility of makingvariations within the scope of the invention as claimed.
